Product Description:

The MLS202S-3A-0300-RN02 is a secondary segment from the Bosch Rexroth Indramat MLS Synchronous Linear Motors series. As a passive reaction plate, it works with a primary coil assembly to generate thrust along a machine’s travel axis. When installed in a gantry, pick-and-place stage, or machining center, the segment provides a continuous iron core that closes the magnetic circuit. This arrangement allows the electromagnetic forces produced by the drive system to create controlled linear motion in industrial automation equipment.

The installation height is held to 77.4 +0.1 mm, minimizing surface deviations when multiple sections are placed end to end. With a linear density of 32.3 kg/m, the assembly adds a predictable load to the axis bearings and supporting structure. Each section measures 300 mm in length, allowing multiple segments to form an extended linear track. The core is made of steel, which provides high magnetic permeability and mechanical stiffness under continuous pull forces. An enclosure rating of IP65 protects the interface against dust ingress and low-pressure water jets commonly encountered around machining fluids and factory washdowns. These physical properties help maintain a consistent air gap between the primary assembly and the secondary track during motion.

The individual segment weighs 9.700 kg, which supports accurate calculations for axis loading, acceleration, and structural deflection. The segment is secured with screws, eliminating the need for adhesives or precision dowels during installation. Mechanical protection is provided by a cover sheet, which shields the poles from metal chips and accidental contact without interfering with the magnetic air gap. The unit uses the S secondary motor type and pairs with the corresponding MLS primary movers in closed-loop servo systems. Its modular form allows adjoining sections to create the required travel distance while preserving the continuous magnetic path needed for linear thrust. Proper alignment of the mounting surface helps distribute mechanical loads evenly across the installed track and reduces variation as the primary mover passes between adjacent segments.
